Abstract
The utility model discloses a Hall oil gas pressure sensor. The Hall oil gas pressure sensor comprises a connector body, a casing body, cable, a plug and an oil hole and further comprises an alloy diaphragm, magnetic steel, a Hall element and a circuit board. According to the Hall oil gas pressure sensor, by adding the Hall element and the circuit board in the device, pressure measurement is carried out by utilizing Hall effect, the Hall oil gas pressure sensor has a firm structure, is convenient to mount and improves measurement precision, moreover, by arranging the alloy diaphragm at the oil hole, and the alloy diaphragm is processed to be in the wave-like shape, so the alloy diaphragm is guaranteed to have characteristics of output linearity displacement according to different pressures, and the magnetic steel is driven to move, and distance measurement pressure of the magnetic steel and the Hall element is changed, and thereby measurement precision is further guaranteed, furtherly, the alloy diaphragm is used, so anti-pollution and anti-corrosion performances of an integral device are improved.
Description
Technical field
The utility model relates to a kind of pressure transducer, specifically a kind of Hall-type oil-air pressure sensor.
Background technology
Pressure transducer is widely used in many different fields, comprises the application such as the automobile such as engine control and tire pressure monitoring, medical instrument field, industrial process control and avionics industry.
At present, domestic and international common oil pressure pressure sensor, adopt measured strain gauge adhesion more at the flexible member of test specimen or sensor, this structure, the formed glue-line of bonding agent just has important effect, the resistance sensitive grid that it will be delivered to elastomeric distortion strainometer accurately gets on, the good and bad operating characteristic that directly affects strainometer of binder performance, but under rugged environment, interference along with extraneous factor, bonding agent is understood the change of characteristic, affects the measurement result of whole pressure transducer; Simultaneously, because the oil-air pressure sensor in use, measured oil gas directly touches the diaphragm in the sensor, and present structure can cause the permanent contaminated and corrosion of diaphragm usually, thereby has further affected the use of single unit system.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of Hall-type oil-air pressure sensor, sound construction, and measuring accuracy is high, further improves simultaneously antipollution and the corrosive nature of device.
To achieve these goals, the technical solution adopted in the utility model is: a kind of Hall-type oil-air pressure sensor, comprise fittings body, cover body, cable, plug and oil through, also comprise the alloy diaphragm, magnet steel and Hall element and circuit board, wherein alloy diaphragm profile is forged as wavy, the centre has groove, be welded on the fittings body by seam, contact with oil gas by oil through, magnet steel is fixed in the groove of alloy diaphragm, Hall element and circuit board are fixed on the top of cover body inside, and circuit board leads is drawn by cable and is connected on the plug in Hall element and the circuit board.
Further, the alloy film sheet material uses stainless steel to be material.
Further, cover body uses stainless steel to be material.
The beneficial effects of the utility model are: by in device, increasing Hall element and circuit board, utilize Hall effect to carry out pressure survey, and sound construction, easy for installation, improved the precision of measuring; Simultaneously at the oil through place alloy diaphragm is set, and be treated to the alloy diaphragm wavy, guaranteed that the alloy diaphragm has the characteristic of output linearity displacement according to the difference of pressure, and the drive magnet steel moves, changed the range observation pressure between magnet steel and the Hall element, thereby further guaranteed the precision of measuring, diaphragm uses the alloy diaphragm simultaneously, has improved antipollution and the corrosive nature of whole device.

Among the figure: 1, fittings body, 2, diaphragm, 3, cover body, 4, magnet steel, 5, Hall element and circuit board, 6, cable, 7, plug, 8, oil through,
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of Hall-type oil-air pressure sensor, comprise fittings body 1, cover body 3, cable 6, plug 7 and oil through 8, also comprise alloy diaphragm 2, magnet steel 4 and Hall element and circuit board 5, alloy diaphragm 2 is wavy, the centre has groove, be welded on the fittings body 1 by seam, magnet steel 4 is fixed in the groove of alloy diaphragm 2, Hall element and circuit board 5 are fixed on the top of cover body 3 inside, and circuit board leads is drawn by cable 6 and is connected on the plug 7 in Hall element and the circuit board 5.
In the utility model, preferred, alloy diaphragm 2 uses stainless steel to be material.Because directly passing through oil through 8, alloy diaphragm 2 contacts with measured oil gas, having adopted stainless steel is material, can further guarantee whole anti-pollution and corrosive nature, guarantee simultaneously still can guarantee original characteristic after alloy diaphragm 2 long-time the uses, further guarantee the accuracy of measuring.
In the utility model, preferred, cover body 3 uses stainless steel to be material.Further guaranteed whole anti-pollution and corrosive nature under abominable working environment.
In the course of the work, measured oil gas contacts with diaphragm 2 by oil through 8, diaphragm 2 has the characteristic of output linearity displacement according to the difference of pressure, because the difference of pressure, the displacement of diaphragm 2 is different, thereby driving magnet steel 4 moves, changed the distance between magnet steel 4 and the Hall element, variation has occured in the magnetic field intensity that acts on the Hall element, obtain force value by detecting this change of magnetic field strength, thereby make Hall element according to the linear signal corresponding to difference output of pressure, measured pressure.
In conjunction with preference and the course of work, the utility model utilizes Hall effect to carry out pressure survey by increase Hall element and circuit board 5 in device, and sound construction is easy for installation, has improved the precision of measuring; Simultaneously at oil through 8 places alloy diaphragm 2 is set, and be treated to alloy diaphragm 2 wavy, guaranteed that alloy diaphragm 2 has the characteristic of output linearity displacement according to the difference of pressure, and the drive magnet steel moves, changed the range observation pressure between magnet steel and the Hall element, thereby further guaranteed the precision of measuring, diaphragm uses alloy diaphragm 2 simultaneously, has improved antipollution and the corrosive nature of whole device.
